Oh, thanks Thomas for the reminder. I just sent a pull request to port python-memcached to Python 3:


I don't understand. I saw a lot of "Port to Python 3" fixes merged in 2014, and these changes are now part of the release 1.54. Problem: running python-memcached tests with tox fail on obvious Python 3 errors. Anyway, all tests now pass with my pull request. The good news is that python-memcached looks to be actively developed.

Julien Danjou ported pymemcache to Python 3, another memcached client. He suggests to use this one instead of python-memcached client.

python-keystoneclient announces a full Python 3 support with a voting Python 3 gate. I just checked locally, "tox -e py34" pass.

The problem is that python-memcached miss in test dependencies and so middleware tests using memcache are never run!
